PAUL A. TRENTEL United States Patent 3,205,520 MOP STRUCTURE Paul A.Trentel, Cleveland, Ohio, assignor to Dir-Fold, Inc. Filed Nov. 27,1962, Ser. No. 249,218 1-3 Claims. (Cl. -119) The present inventionrelates generally to novel and improved structural arrangements whichare particularly adapted to mops, and more specifically to improvementsin the construction of squeeze mops.

Various types of squeeze mops have been provided in the past. While incertain aspects the invention has general applicability to all forms ofmops, as well as to other structures, the invention is especially suitedto that type of squeeze mop wherein a cleaning member, such as a sponge,is carried on a backing plate which is connected to a handle and acontrol or squeeze plate is associated with the backing plate inposition to be swung over and compress the sponge to force watertherefrom. Although this type of squeeze mop has had relatively widecommercial acceptance, certain disadvantages associated with the priorart constructions have limited their versatility and have made themrelatively expensive.

For example, the sponge cleaning member is customarily mounted at afixed angle with relation to the mop handle so that it is difficult, ifnot impossible, to use the mop for cleaning under various articles, suchas furniture and the like. Further, the usual mop having the sponge at afixed angle to its handle cannot be conveniently and effectively used toclean walls and other surfaces which are not horizontal. Most prior artattempts to provide a squeeze mop having an angularly movable sponge mophead have been unacceptable because of the complexity of theconstruction involved and a characteristically diflicult andinconvenient manner of use. Moreover, such con ventional constructionsusually have not been structurally stable and tend to collapse whenpressure is applied to the handle during a cleaning operation.

Another objection to conventional sponge mop constructions, as well asto other mop structures, is the relatively high cost of manufacturewhich results in part from manual assembly operations that have beenrequired. One such manual assembly operation has been the connection ofthe mop handle to the mop head. Customarily, this has been achieved by ahandle socket and a pin which is secured through the end of the handlein the handle socket. Other conventional constructions have been to forma threaded end on the handle which is secured. into a correspondinglythreaded socket, and to provide a split handle socket in which thehandle is secured by a clamping nut, such as a wing nut or the like.Each of these prior art practices has been expensive and has involvedmanual assembly operations which the present invention avoids.

A general object of the present invention is to provide a novel andimproved adjustable angle mounting construction which permits anassociated member, and particularly a force-transmitting member, to beadjusted and securely locked in a plurality of angularly relatedpositions.

A more specific object of the invention is to provide a novel andimproved squeeze mop of the type described which is characterized by theprovision of an adjustable angle mounting construction for the mop head,whereby the mop head can be adjusted and locked in a plurality ofdifferent angular positions with respect to the handle of the mop soasto adopt the mop for a variety of cleaning operations.

Another object of the invention is to provide a novel and improvedsqueeze mop wherein the mop head can be adjusted from a position whereits working surface is angularly related with respect to the handle ofthe mop to a position where the working surface is parallel to andoffset from the handle.

A further object of the invention is to provide improvements in themanufacture of mop structures, and particularly in the manner ofconnecting the handles of the mops to the mop heads.

In accordance with the preferred form of the invention, the adjustableangle mounting construction, which is shown for purposes of disclosureas being embodied in a squeeze mop of the type described, includes apivotal connection between a mop head plate for the cleaning member anda carrier bracket at the end of the mop handle, the pivotal connectionbeing transverse to the longitudinal axis of the handle. The head plateis provided with a locking rib construction which cooperates tofrictionally engage the carrier bracket and hold the mop head in aposition of angular adjustment with respect to the mop handle. Anactuating handle is connected. to the head plate and is provided with anoffset portion which cooperates with a recess formed in the carrierbracket to hold the mop head in another position wherein the workingsurface of the cleaning member is generally parallel to the mop handle.In this latter position, the squeeze mop can be conveniently and easilyused to clean under low objects, such as furniture and the like, and toclean vertical walls and other surfaces.

Although a sponge cleaning member is usually provided, the inventioncontemplates a releasable connection between the cleaning member and thehead plate so that different cleaning members, including buffers, waxingheads, and other implements, can be easily substituted for the disclosedsponge cleaning member. As will be discussed in more detail, theadjustable angle mounting construction and the releasable connection forthe cleaning member cooperate to facilitate a wide variety of cleaningand other operations.

Another novel and improved feature of the invention which is applicableto mop structures in general, as well as to other constructions, is theimproved manner of connecting the handle to the mop head. In theillustrated embodiment of the invention, this connection contemplates asplit socket construction which forms a part of the carrier bracket andwhich receives one end of the mop handle. Opposite sides of the split,socket are forced toward each other by a coil spring to securely clampthe mop handle in the socket. Because of this construction, the mophandle can be quickly attached to the carrier bracket during assembly ofthe mop. Moreover, it is easy to thereafter replace the handle by simplyseparating the socket.

Other objects and advantages of the invention will become apparent fromthe following detailed description and the accompanying drawings.

' FIGURE 9 is a plan view, partially broken away, showing portions of afurther modified mop construction of the invention; and

FIGURE 10 is an enlarged, fragmentary cross-sectional view taken on theline 1010 of FIG. 9.

Referring now to the drawings, and to the preferred embodiment of FIGS.1-7 in particular, the squeeze mop construction which embodies theprinciples of the invention is generally indicated by reference numeral11. As shown, this squeeze mop construction includes a handle 12 towhich the mop head structure is connected by a carrier bracket 13.

In accordance with the foregoing objects and advantages of theinvention, the carrier bracket 13 is adapted to engage and secure themop head structure to the handle 12 in a novel and improved manner. Tothis end, the carrier bracket 13 is provided with an integral tubularsection 14 in the form ,of a split handle-receiving socket.Substantially parallel, adjacent flanges 16 and 17 (FIG. are formedalong the edges of the split tubular section 14 and receive means, suchas a rivet 18, which carries a coil spring 19 that forces the edgeflanges toward each other in a resilient manner. If desired, the tubularsection 14 may be lanced or punched to provide an inwardly extendingtank 14a. The provision of this tang assures against rotation of thehandle 12.

By means of the novel handle securing construction,-the

mop can be assembled quickly and easily by forcing the 'handle 12endwise into effective gripping engagement. be-

tween the side flanges 16 and 17. Since the handle usually is wood thetang 14a will become embedded in the end portion of the handle when itis inserted between the flanges. Also, it will be seen that the sideflanges 16 and 17 can be separated to facilitate removal and replacementof the mop handle.

As shown, the carrier bracket 13 further includes parallel ear sections20 which extend laterally from the axis of the mop handle 12. These earsections 20 are formed with inwardly extending flanges 21 (FIG. 7) whichdefine an axially inclined, end abutment surface. An aperture 22 may beprovided in the end of the carrier bracket opposite the split socket 14for use in hanging the mop 11 on a suitable hook or hanger.

An elongated head plate 23 is provided in the squeeze mop construction11 and a bracket 24 is secured to the upper surface of this head plateintermediate its ends. The bracket 24 has a pair of spaced,substantially parallel ears 24a which extend from the top surface of thehead plate 23 between its ends and on one side edge thereof. Theextending ears 24a of the head'plate 23 are pivotally connected to theear sections 20 of the carrier bracket 13, as by a rivet or equivalentmember 25 adjacent one edge of the abutment'surface defined by theflanges 21. This offset pivotal connection which is provided issuch-that the head plate 23 can be moved between one position in whichthe major portion of the head plate is contiguous to the flanges 21(FIG. 3) and another-position in which the head plate 23 issubstantially parallel to the longitudinal axis of the carrier bracket(FIG. 2).

' The bracket 24 also includes a pair of spaced, upstanding locking ribs24b. As most clearly shown in FIG. 1, these ribs 24b are formed withslightly' inturned end portions 240 for frictionally engaging thecarrier bracket ear sections 20,- 20 to securely hold the head plate inthe position illustrated in FIG. 3. It will be apparent from thisconstruction that, when the mop head plate is at the illustratedoperative angle to the longitudinal axis of the handle 12, thecooperative engagement of the abutment.

4 flanges 21 with the head plate and of the locking ribs 24b with theouter surfaces of the ears 20 assure a strong, stable construction thatwill not collapse under the force exerted through the mop handle.

The mop head plate 23 has a downwardly extending flange 27 which isintegrally formed along the ends and forward edge of the plate, and acleaning member 28 is suitably connected to the mop head plate withinthe confines of this edge flange 27. In the illustrated embodiment ofthe invention which is shown to employ a sponge of any suitableconstruction as the cleaning member, a sponge backing plate 29 isprovided on the upper surface of the sponge (FIG. 7). This backing plate29 has a plurality of small apertures 30 and rough protruding edgeportions 31 formed around the apertures. These protruding edge portions31 maybe provided by punching the backing plate 29 to form theapertures'30 or by otherwise roughening the lower surface of the backingplate. By providing a backing plate having a roughened surface andcoating this surface with a suitable adhesive cement, the sponge 28 canbe firmly connected to the backing p ate.

The sponge backingplate 29. preferably is'removably secured to the mophead plate 23. in order to facilitate replacement of the sponge and topermit other cleaning implements to be used. To this end, a pair ofintegrally formed tabs 32 extend from the backing plate 29 throughcooperating slots 33 formed in the mophead plate 23. As best shown inFIG. 6, the tabs. 32 are struck from the backing plate 29 and are bentover the upper surface of the head plate 23 to form a releasableconnection there with. It will be understood, of course, that the sponge28 can be connected to the plate 23 by different means than thatspecifically shown in the drawings. For example, it may be desirable toconnect the sponge or other cleaning member by threaded studs which arereceived through the head plate and secured by wing nuts or the like. Tothis end, the tab slots 33 are shown as being formed with centrallylocated hole-s 33a which are adapted to receive the connecting studs(not shown). In another arrangement, the backing plate 29 maybeeliminated and the sponge connected to the plate 23 by an embedded wireclip which cooperates with the flanges 27 to hold the sponge in place.

The squeeze mop 11 also includes an elongated squeeze plate 34 that isof substantially the same shape as the mop head plate 23 but of slightlylarger size. This squeeze plate 34 is pivotally attached to the rearwardside edge of the mop head plate, as by a hinge pintle or pin 35. Asshown, the squeeze plate 34 has a hinge edge'portion 34a which is offsetfrom the general plane defined by the squeeze plate 34 so that thesqueeze plate is, in turn, offset slightly from the plane of the mophead plate 23. As will hereinafter be described in more detail, thisoffset construction facilitates the squeezing action of the squeezeplate to aid in confining the sponge 28 and flanges 34b and a side edgeflange 34c (FIG. 7) which extend at an angle from the generally flatsurface of the squeeze plate to aid in confining the sponge 28 andforcing water therefrom, as indicated in FIG.4. The squeezing action andpositionof the squeeze plate 34 is controlled by an actuating handlemember 36 secured to the rear surface of the squeeze plate, as by arivet 37 (FIG. 7). It will be seen that the provision of a sponge 28having a parallogram shape facilitates the swinging of the squeeze plate34 into operative compressive engagement with the sponge without acounteracting, excessive force being exerted along the edge of thesponge mop adjacent the hinge pin 35.

A releasable lock construction is provided to secure the mop head intheposition illustrated in FIGS. 2 and 7. As shown, the lock'constructionis formed by an offset shoulder portion 38 on the actuating handle 36anda cooperating recess or notch 39 formed in the upper ends of the edgeflanges 16 and 17 of the carrier bracket 13.

This lock construction is such that the actuating handle 36 can bepulled generally upwardly along the handle 12 and parallel to the axisof the tubular section 14 to move the shoulder 38 axially beyond theends of the edge flanges 16 and 17. The handle then is swung in behindthe flanges to engage the shoulder within the notch or recess 39 asshown in FIG. 7.

The above locking action is against the resilient action of a coilspring 40 which is suitably engaged with and carried by the assembly ofthe mop head plate 23 and the squeeze plate 34, the coil spring 40normally acting to urge the squeeze plate and the mop head plate apart.As shown, the coil spring 40 is positioned on the hinge pin 35 and hasone end 40a thereof engaging the lower surface of the mop head plate 23so that it is biased toward the inclined flange surfaces 21 of thecarrier bracket 13. The other end 40b of the coil spring 40 engages thefront undersurface of the squeeze plate 34 so that the squeeze plate isurged towards the edge flanges 16 and 17.

It will be seen from the illustrated construction that, when theactuating handle 36 is pulled upwardly to effect the described lockingaction, the mop head plate 23 will be pivoted against the biasing actionof the coil spring 40. Thus, when the lock is released by axiallypulling the handle 36 to disengage the shoulder 38 from within the notch39, the spring 40 will again urge the mop head plate 23 into contactwith the flange surfaces 21 of the carrier bracket 13. If necessary, aslight compressive force can be exerted against the mop head plate 23through the handle 36 so as to force the locking ribs 24b into positiveengagement with the associated outer surfaces of the ears 20 of thecarrier bracket.

FIGURE 8 shows a modification of the invention wherein a sponge 118 isin direct engagement with a mop head plate 111. A plurality of roughsurfaced apertures 120 are formed in the plate 111 and the sponge 118 isdirectly cemented thereto by a layer of suitable adhesive 122. Theroughened surfaces and the projecting metal portions around theapertures 120 again facilitate a good bond between the sponge and theplate to which it is secured.

FIGURES 9 and show a further modification of the sponge cleaning memberand the connection between the sponge and the mop head plate. In thisembodiment, the mop head plate 211 carries a backing plate 219 securedthereto. This backing plate 219 is received between end flanges 217 ofthe mop head plate, and a pair of end securing tabs 220 are provided onthe backing plate 219 to be folded over and passed through slots 221formed in the end flanges 217, whereby a good interlocking engagement isobtained between the backing plate 219 and the mop head plate. Thesponge 223 is preferably secured to the backing plate by an adhesivelayer 222 in the same manner as the structures shown in FIGS. 1-7.

As used herein, the term adjustable angle mounting construction will beunderstood to include the structure of the mop head plate, the offsetpivotal connection between the head plate and the relatively fixedcarrier bracket 13, the locking rib formation 24!; which cooperates withthe carrier bracket to maintain the head plate in one position ofangular adjustment against an abutment surface of the carrier bracket,the biasing spring 40 and the locking arrangement formed by theactuating handle 36 and a portion of the carrier bracket whichcooperates to secure the head plate in another position of angularadjustment.

While especially adapted for squeeze mops of the type described, thenovel adjustable angle mounting construction also is useful in othertypes of structures requiring an angularly adjustable mounting bracket,and particularly a bracket capable of being easily manipulated andwithstanding loads in each position of adjustment. As will be apparentfrom the above description, these advantages are obtained with theinvention by the spring 40 which abutment surfaces 21 of the carrierbracket 13 and the.

locking ribs 24b which engage the sides of the carrier bracket. In thisposition a load can be exerted along the mop handle without causing theadjustable angle mounting construction to move or collapse.

By simply pulling the actuating handle 36 and manipulating the offsetshoulder portion 38 into the locking recess 39, the head plate can bepivoted and locked in a position substantially parallel to the axis ofthe carrier bracket. When the handle 36 is subsequently released fromengagement with the carrier bracket, the head plate will be spring-urgedtoward its former position.

In the position illustrated in FIGS. 2 and 7, the squeeze mop can beused conveniently to clean under furniture and other objects. Moreover,the mop can be used effectively to clean Walls and similar surfaceswhich require that the mop handle be generally parallel to the workingsurface of the cleaning member. This unique versatility further isenhanced since the disclosed sponge can be easily and quickly replacedby other cleaning implements, and the position of the mounting headadjusted to suit the desired operation which is to beperformed.

It will be understood that the novel and improved tubular connectingconstruction which comprises another aspect of the invention andincludes the split socket 14 and the clamping spring 19 also hasapplicability in other environments, since it provides a means by whicha handle can be easily connected and disconnected with associatedstructure. As distinguished from prior art arrangements, thisconstruction does not require special threading on the handle or otherexpensive connecting provisions, such as a connecting pin or the like.Another advantage which is particularly utilized in the disclosedarrangement of the squeeze mop employing an adjustable angle mounting.

construction is that the illustrated straight mop handle can be replacedby handles of different configurations which are best suited to theversatile cleaning operations that can be performed with the novel mopstructure. For
